Fix Android Studio Build Tools Version:

You can change the build tools version to the latest installed version.

Open your “app” folder and find the “build.gradle” file inside that folder.

Note: there is another “build.gradle” file in the “Gradle Scripts” folder – that is not the file you want.

buildgradle

Change the value of the “buildToolsVersion” attribute to a different version number.

buildtoolsversion

As of Spring 2017, we have version 23.0.3 installed, so you change that last “2” to a “3” and make it work.  You can also use a later version (it’s recommended to use the latest version).

Check which versions you have installed from the menu screen (you have to close your projects to get there).

  • Click “Configure,” then “SDK Manager.”
  • Click the “SDK Tools” tab.
  • Click “Show Package Details” checkbox at the bottom right.
  • Check which version numbers you have installed under “Android SDK Build-Tools.”
